Water-injected 2.0-liter turbo-four hydrogen engine spits out 410 hp
Austrian mobility technology company AVL had a pretty good day for itself earlier this month, when it confirmed simulations that showed its prototype 2.0-liter turbo hydrogen race engine developing over 200 hp-per-liter. AVL uses a water-injection system alongside its turbocharger to moderate combustion for safer burn and improved power production ... and so far it's working like a charm. Most of the fanfare around automotive hydrogen has been related to fuel cell-electric powertrains, but hydrogen combustion engines have…
